Dwyer Instruments, the preferred source for your complete range of practical and affordable instrumentation is announcing the release of the Series DAFA Air Flow Indicator and Alarm. The Air Flow Indicator and Alarm is designed to alert users of low or no air flow conditions in pipes. The DAFA is ideal for monitoring radon mitigation systems by detecting a loss of air flow in the pipe and providing a signal to the homeowners if the fan has stopped operating.
The Air Flow Indicator and Alarm utilizes a thin, field-trimmable vane to sense the air flow rate in pipe sizes between three to four inches. The DAFA is battery powered to provide versatility of installation location and offers a yellow LED to indicate a low battery. In addition, the battery can last up to five years when in a steady state. An 85 dB audible buzzer alternates with a bright red LED to alert users when the air flow rate drops below the desired rate.
